Abstract

PROBLEM TO BE SOLVED: To form a protrusion part extending in the longitudinal direction in an outer peripheral side face of a hydraulic solidification material liquid substitution column so that a vertical bearing force of the column on the peripheral ground can increase.SOLUTION: In a lower part of an excavation rod 1, a cylindrical body 4 including a projection body having a rotation diameter greater than a diameter of the excavation rod 1 is loosely fitted around the excavation rod 1 in a rotatable manner.SELECTED DRAWING: Figure 1

【課題】水硬性固化材液置換コラム外周側面に縦方向に延びる突条部を形成して、周辺地盤におけるコラムの鉛直支持力を増大可能にする。【解決手段】掘削ロッド１下方部に、回転径が該掘削ロッド１径よりも大きい突出体を有する円筒体４を、掘削ロッド１の周りに回転可能に遊嵌させた構成である。【選択図】図１
